HAR ES T EITZ 2 2o 3 2 FIG 2 BY I ATTORNEY United States Patent 3,361,093 INCINERATOR Charles T. Heitz, 315 NE. 28th, Portland, Oreg. 97232 Filed Aug. 31, 1965, Ser. No. 483,934 4 Claims. (Cl. 11018) ABSTRACT OF THE DISCLOSURE An incinerator having a perforated lid at its upper end and a perforated grate at its lower end supported on inwardly bent tongues struck from the side walls of the incinerator. The grate is supported above the bottom of the incinerator and is smaller in diameter than the incinerator to provide a side draft. Such grate also has a downturned rim forreinforcement as well as to be mounted against lateral movement on the tongues, the latter preferably being curved longitudinally such that the tips thereof project upwardly to engage the under surface of the grate.

This invention relates to new and useful improvements in incinerators and particularly is concerned with incinerators of a size and application intended for home use.

A primary objective of the present invention is to provide an incinerator which is simplified in construction and eflicient in operation.

A more particular object is to provide an incinerator utilizing a barrel-type construction and a novel formation of grate holding means in the barrel.

It is another object to provide an incinerator having a barrel-type construction wherein a lower grate thereof is supported on inwardly directed tongues comprising portions of the side walls of the barrel which have been punched out on all but one connecting side and bent inwardly.

Still another object is to provide a novel arrangement of grate and means for confining burning material within the incinerator.

Briefly stated, the invention comprises a barrel-type container having a perforated lid and a lower grate. The lower grate is supported on inwardly directed tongues forming a part of the walls of the barrel and more particularly comprising inwardly bent, partially punched out portions of the barrel walls. Also incorporated in the structure below the grate is screen means for confining the fire within the barrel.

The invention will be better understood and additional objects will become apparent from the following specification and claims, considered together with the accompanying drawings, wherein the numerals of reference indicate like parts.

In the drawings:

FIGURE 1 is a side elevational view, partly broken away, of an incinerator embodying the principles of the present invention;

FIGURE 2 is a top plan view with parts thereof broken away, taken on the line 22 of FIGURE 1;

FIGURE 3 is a foreshortened, offset sectional view taken on the line 3-3 of FIGURE 2;

FIGURES 4 and 5 are fragmentary elevational views showing other shapes of tongues which may be partially cut from the wall portions of the barrel and bent inwardly for supporting the bottom grate; and

FIGURES 6 and 7 are fragmentary sectional views showing different dispositions of such partially punched out portions with relation to the interior of the barrel.

Referring now in particular to the drawings, and first to FIGURES 1, 2 and 3, the present incinerator comprises a container or body portion 10 which may assume simply a conventional barrel-type construction. The incinerator utilizes a lid or cover 12 having a plurality of perforations 14 therein and having an outer inverted char1- nel-type peripheral socket 16 adapted to seat on a peripheral rib 18. Lid 12 is removably seated on the body portion of the barrel.

The incinerator employs a grate 2t) interiorly thereof disposed at its lower portion. This grate has a plurality of apertures 22 therein of the usual diameter capable of supporting material to be burned thereon,'but at the same time allowing a good draft up the barrel. This grate preferably has a down-turned peripheral rim 24 for a purpose to be explained hereinafter. The spacing and size of the apertures in the grate 20 and in the lid 14 may vary, but as seen in FIGURE 2 to accomplish an eflicient op eration it has been found that the apertures 22 are somewhat enlarged relative to the apertures 14 and the number of apertures 14 is approximately double per given area relative to the apertures 22. The grate 20 is smaller in diameter than the container to allow a good draft to circulate at the sides.

The grate 20 is supported on tongues 26 leading inwardly from the sides of the container. In a preferred construction, the tongues comprise portions of the container walls which are cut in their outline on all sides except an upper portion 28 thereof. With the connections of the tongues at only the upper ends thereof, they are capable of being bent inwardly to the position shown in FIGURES 2 and 3 to form a support for the grate. The cutting of the tongues and inward bending and shaping thereof may be accomplished by any suitable tool.

Referring particularly to FIGURE 1, the tongues may assume a triangular shape with the connecting portion 28 comprising one side of the triangle. Preferably, as seen in FIGURE 3 the tongues are arcuate along their longitudinal axes whereby the free ends thereof are arranged to engage the undersurface of the grate 20 inside of the rim 24 of said grate. With this type of engagement between the supporting tongues 26 and the grate, the grate cannot slide laterally and become accidentally displaced from its support.

FIGURES 4 and 5 show different tongue shapes 26a and 26b, respectively. These views demonstrate the fact that the tongues may assume almost any desired shape. For example, in FIGURE 4 the tongues 26a are rectangular in configuration and FIGURES 5 the tongues 2612 are circular.

FIGURES 6 and 7 illustrate that the tongues 260 may be straight rather than arcuate along their longitudinal plane, as shown in FIGURE 3, and furthermore may be angled upwardly, as in FIGURE 6, or downwardly, as in FIGURE 7. In all cases they form a support for the grate 20. It is to be understood that the tongues 26 may assume any desired shape, and may be directed inwardly at various angles of support for the grate 20.

The container 10 has a bottom wall 32 of imperforate construction. This wall is connected to the said container by any suitable means such as by a socket and rim c0nstruotion 16, 18 similar to the lid 12.

Disposed around the inner periphery of the container 10 in vertical position between the tongues 26 and the bottom of the container is a band 34 of a mesh material such as screen permitting the entrance of a draft through the holes from which the tongues 26 were cut but preventing any outward movement of ashes through said holes. In a preferred construction, the screen band 34 is of a selected width such that it fits snugly in. engagement with the tongues 26 at the upper connecting portions 28 thereof and in engagement with the inner surface of the bottom wall 32. Thus, for installation purposes the screen band 34 may be installed peripherally of the container 10 in place against the tongues 26 and then the bottom wall 32 installed for holding the band in place.

The container is supported on suitable legs 36 integrated, such as by welding, to the bottom wall 32.

In accordance with the present invention it will be seen that an incinerator is provided which is extremely simplitied in construction but efficient in use. It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims. For example, the container or body portion 10 may assume shapes other than the round shape shown, such as rectangular, hexagonal, or the like.

Having thus described my invention, 1 claim:

1. An incinerator construction comprising a tubular body portion having a bottom wall and a removable lid, said lid being perforated, a transversely disposed grate in said body portion, inwardly disposed tongues integrated with the walls of said body portion for supporting the grate above the bottom of said container, said tongues comprising inwardly bent portions punched from the walls of said body portion, and screen band means extending peripherally around the inner surface of the container between the said tongues and the said bottom wall and covering the hole portions made by the punched portions of the container walls.

2. The incinerator construction of claim 1 wherein said grate is of less diameter than the inner diameter of said body portion to form a peripheral space between said grate and body portion to allow a draft to circulate from said punched out hole portions up through said space as well as through the perforated grate.

3. The incinerator construction of claim 1 wherein said tongues are curved longitudinally such that the tip ends thereof project upwardly for engaging the under surface of said grate for supporting the latter.

4. The incinerator construction of claim 1 wherein said grate is of less diameter than the inner diameter of said body portion to form a peripheral space between said grate and body portion to allow a draft to circulate from said punched out hole portions up through said space as well as through the perforated grate, said tongues being curved longitudinally such that the tip ends thereof project upwardly for engaging the under surface of said grate for supporting the latter, said grate having a downturned edge rim, said tip ends of the tongues engaging the under surface of said grate inwardly of and adjacent to said rim whereby the grate is held against lateral movement on said tongues.
